Description

Technical Field

[0001] The utility model relates to the technical field of sealing film positioning, in particular to a sealing film positioning device for a filling machine and a film sealing machine. Background Art

[0002] When using a filling machine to seal the container mouth of a container body with a film, a sheet-shaped film adapted to the shape of the container mouth is required; the existing general methods for placing the sealing film are manual placement and suction cup placement; manual placement has the risk of product contamination and low efficiency; suction cup placement can improve work efficiency, but there are also cases where the position deviation of the sealing film is large and there are defective products with white leakage, resulting in a reduction in the qualified rate of product outer packaging.

[0003] Chinese Patent (Grant Publication No. CN 219097160 U, Grant Publication Date: May 30, 2023) discloses a film sealing machine. Its feeding table protrudes inward along the radial direction of the heating through-hole at both ends of the heating through-hole, making the heating through-hole have a shape that is narrow at both ends and thick in the middle. Its suction cup is aligned with the heating through-hole and the suction cup is pushed into the heating through-hole by a pushing and pulling part. Since the heating through-hole has a shape that is narrow at both ends and thick in the middle, the film will not fall out of the heating through-hole, ensuring that the feeding table can smoothly transport the film to the heating position. It can be seen that the heating through-hole with a shape that is narrow at both ends and thick in the middle can only restrain the film in the heating through-hole to prevent the film from falling out, but cannot accurately guide and position the film. When the film is in the sealing position, there will still be a deviation in the sealing position, and the defective rate of product sealing cannot be effectively reduced.

[0004] Therefore, how to provide a sealing film positioning device for a filling machine and a film sealing machine that can accurately guide the sealing film so that the sealing film is accurately positioned at the container mouth of the container to be sealed is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0005] In view of this, the utility model provides a sealing film positioning device for a filling machine and a film sealing machine, aiming to solve the technical problem that the sealing film cannot be accurately positioned at the container mouth during film heating and sealing, resulting in a high defective rate of product sealing.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] On the one hand, the utility model provides a sealing film positioning device for a filling machine. The container to be filled is arranged on the filling table of the filling machine, and it includes:

[0008] An annular base, the annular hole of the annular base is a positioning hole that can be adaptively sleeved on the outer peripheral side of the container to be filled;

[0009] A plurality of guide post assemblies, and the plurality of guide post assemblies are vertically installed on the annular base at circumferential intervals along the annular base and can all be lifted and lowered; the upper ends of the plurality of guide post assemblies can all be located above the annular base and jointly enclose a sealing film guiding channel; the upper part of the sealing film guiding channel is a frustum-shaped rough positioning guiding channel with a large upper opening and a small lower opening, and the lower part of the sealing film guiding channel is a cylindrical precise positioning guiding channel adapted to the outer contour of the container mouth of the container to be filled.

[0010] A sealing film positioning device for a filling machine according to the present invention, when in use, the annular base is sleeved on the outer periphery of the container to be filled, and the sealing film guiding channel formed by enclosing the upper ends of the plurality of guide post assemblies is arranged directly above the container mouth of the container to be filled; the suction cup is used to suck the sealing film and release it directly above the sealing film guiding channel. The sealing film first falls smoothly under the guiding action of the frustum-shaped rough positioning guiding channel to gradually correct the position, and then enters the cylindrical precise positioning guiding channel for precise guiding and positioning, and finally realizes precise positioning at the upper end of the container mouth of the container to be filled. The liftable guide post assembly can avoid the film heat-sealing press head when the film heat-sealing press head descends to press the heat-sealed sealing film, and will not interfere with its heat-sealing operation; the structure of the present invention is simple, easy to manufacture and arrange, and for the sealing film with lugs, the lugs of the sealing film can be placed corresponding to the interval between two adjacent guide post assemblies, which will not affect the guiding effect of the sealing film guiding channel, so as to ensure the precise positioning of the whole sealing film at the upper end of the container mouth of the container to be filled.

[0011] As a further improvement of the above technical solution, the tops of the plurality of guide post assemblies all have conical sections along their height directions, and the conical sections enclose to form the frustum-shaped rough positioning guiding channel.

[0012] The beneficial effect of the above technical solution is that the frustum-shaped rough positioning guiding channel can be constructed by designing the top of each guide post assembly as a conical section, which is convenient for processing and manufacturing, and the manufacturing cost is low.

[0013] As a further improvement of the above technical solution, the guide post assembly includes a guide post that is elastically liftable and slidably connected to the annular base along the height direction of the annular base;

[0014] The top of the guide post has a conical section along its height direction; the top end of the conical section is a downward pressing end that can be in contact with the film heat-sealing press head; the downward pressing end can be lowered to be flush with the sealing surface at the upper end of the container mouth of the container to be filled under the pressing and pushing action of the film heat-sealing press head.

[0015] The beneficial effects of the above technical solution are as follows: To avoid the guide posts interfering with the diaphragm heat-sealing press head from thermally pressing the sealing diaphragm, the guide posts are designed as elastically liftable guide posts, so that when the diaphragm heat-sealing press head abuts against the lower pressing end, the guide posts can synchronously descend as the diaphragm heat-sealing press head descends; the lower pressing end can descend and yield to the upper sealing surface of the container mouth of the container to be filled, so as to ensure that the diaphragm heat-sealing press head can smoothly press and thermally seal the sealing diaphragm on the container mouth of the container to be filled. During the descent of multiple guide posts, the peripheral wall of the cylindrical precise positioning guide channel thereof can contact and friction the periphery of the sealing diaphragm, so as to ensure that the position of the sealing diaphragm is accurately positioned and the bottom surface always fits on the upper end of the container mouth.

[0016] As a further improvement of the above technical solution, the guide post assembly further includes an elastic component, one end of the elastic component is arranged on the annular base, and the other end is connected to the lower end of the guide post, so that the guide post can elastically lift along the height direction of the annular base.

[0017] The beneficial effects of the above technical solution are as follows: The elastic component plays a role in providing lifting elastic force for the guide post. During the process of the diaphragm heat-sealing press head resetting upward after the sealing is completed, the elastic component drives the guide post to rise and reset, so as to continuously perform the positioning operation of the sealing diaphragm.

[0018] As a further improvement of the above technical solution, a plurality of guide through holes are opened in the annular base along the height direction, and the guide posts are respectively and slidably inserted through the plurality of guide through holes; the elastic component is a spring movably sleeved on the lower end of the guide post, its upper end corresponds to the lower part of the cylindrical precise positioning guide channel and is connected to the guide post, and its lower end abuts against the top end of the annular base to provide elastic force when the guide post lifts.

[0019] The beneficial effects of the above technical solution are as follows: The guide through holes play an accurate guiding role in the lifting of the guide posts, and a spring is sleeved on the guide posts to provide elastic force, and the structure is more compact.

[0020] As a further improvement of the above technical solution, the diameter of the bottom end of the guide post is larger than the aperture of the guide through hole.

[0021] The beneficial effects of the above technical solution are as follows: The diameter of the bottom end of the guide post is larger than the aperture of the guide through hole, which can prevent the guide post from being disengaged from the guide through hole when rising upward.

[0022] On the other hand, the present utility model provides a sheet film sealing machine, including the above-mentioned sealing diaphragm positioning device for a filling machine, a diaphragm heat-sealing press head, a press head lifting mechanism, a diaphragm suction cup, a robotic arm, and a diaphragm placement container;

[0023] The container to be filled is arranged on the filling table; the annular base is sleeved on the outer periphery of the container to be filled; the bottom port of the cylindrical precise positioning guide channel corresponds to the top end of the container mouth of the container to be filled;

[0024] The indenter lifting mechanism, the robotic arm, and the diaphragm placement container are all arranged around the filling table; the end of the robotic arm is equipped with a diaphragm suction cup to drive the diaphragm suction cup to suck the sealing diaphragm from the diaphragm placement container and transfer the sucked sealing diaphragm to above the corresponding frustum-shaped rough positioning and guiding channel for release;

[0025] The diaphragm heat-sealing indenter is installed at the lifting end of the indenter lifting mechanism, and its bottom end corresponds to above multiple guiding column assemblies, and can descend to press and drive multiple guiding column assemblies to descend, and press and heat-seal the sealing diaphragm on the top end of the container mouth of the container to be filled.

[0026] When a diaphragm sealing machine of the present utility model is in use, the sealing diaphragm is sucked and released by the diaphragm suction cup, and the sealing diaphragm can be placed directly above the frustum-shaped rough positioning and guiding channel for release by the robotic arm. The frustum-shaped rough positioning and guiding channel can guide and correct the placement deviation of the sealing diaphragm, so that the sealing diaphragm can smoothly enter the cylindrical precise positioning and guiding channel and accurately fall on the top end of the container mouth of the container to be filled. The indenter lifting mechanism can drive the diaphragm heat-sealing indenter to move up and down. The bottom end surface of the diaphragm heat-sealing indenter presses against the top end of the guiding column assembly, so that the guiding column assembly descends to avoid the diaphragm heat-sealing indenter, and finally realizes the pressing and heat-sealing of the sealing diaphragm by the diaphragm heat-sealing indenter.

[0027] As a further improvement of the above technical solution, the diaphragm heat-sealing indenter is an electromagnetic induction heating indenter to perform electromagnetic heating and sealing on the sealing diaphragm when approaching the sealing diaphragm.

[0028] As a further improvement of the above technical solution, the sealing diaphragm is an electromagnetic induction sealing diaphragm.

[0029] It can be seen from the above technical solutions that compared with the prior art, the present utility model discloses a sealing diaphragm positioning device for a filling machine and a diaphragm sealing machine, which has the following advantages and beneficial effects:

[0030] 1. The present utility model forms a sealing diaphragm guiding channel that matches the outer contour of the container mouth of the container to be filled by enclosing multiple guiding column assemblies; and corrects the position of the sealing diaphragm through the frustum-shaped rough positioning and guiding channel, and precisely positions the sealing diaphragm through the cylindrical precise positioning and guiding channel, effectively improving the sealing quality rate.

[0031] 2. The present utility model designs the guiding column to be elastically liftable under the pressure of the diaphragm heat-sealing indenter, so there is no need for the diaphragm heat-sealing indenter in the diaphragm sealing machine of the filling machine to enter the sealing diaphragm guiding channel for heat-sealing work, nor is it necessary to disassemble the sealing diaphragm positioning device, making it more convenient and efficient to use.

[0042] An annular base 1, the annular hole of the annular base 1 is a positioning hole 12 that can be adaptively sleeved on the outer peripheral side of the container 4 to be filled;

[0043] A plurality of guide post assemblies 2, the plurality of guide post assemblies 2 are arranged at intervals along the circumferential direction of the annular base 1 and are vertically installed on the annular base 1 and can all be lifted and lowered; the upper ends of the plurality of guide post assemblies 2 can all be located above the annular base 1 and jointly enclose a sealing film guiding channel 211; the upper part of the sealing film guiding channel 211 is a frustum-shaped rough positioning guiding channel 2111 with a large upper opening and a small lower opening, and the lower part of the sealing film guiding channel 211 is a cylindrical fine positioning guiding channel 2112 adapted to the outer contour of the container opening of the container 4 to be filled.

[0044] A positioning device for sealing film of a filling machine according to this embodiment, when in use, sleeved the annular base 1 on the outer periphery of the container 4 to be filled, and arranged the sealing film guiding channel 211 formed by enclosing the upper ends of a plurality of guiding column assemblies 2 directly above the container opening of the container 4 to be filled; suck the sealing film by a suction cup and release it directly above the sealing film guiding channel 211. The sealing film first falls smoothly under the guiding action of the frustum-shaped rough positioning guiding channel 2111 to gradually correct the position, and then enters the cylindrical fine positioning guiding channel 2112 for precise guiding and positioning, and finally realizes precise positioning at the upper end of the container opening of the container 4 to be filled. The liftable guiding column assembly can descend synchronously with the film heat-sealing press head, and will not interfere with the heat-sealing operation of the film heat-sealing press head on the sealing film. The structure of the utility model is simple, convenient for manufacturing and arranging, and for the sealing film with lugs, the lugs of the sealing film can be placed corresponding to the interval between two adjacent guiding column assemblies 2, which will not affect the guiding effect of the sealing film guiding channel 211, so as to ensure the precise positioning of the whole sealing film at the upper end of the container opening of the container 4 to be filled.

[0045] Specifically, the annular base 1 can be fixed on the upper end of the filling table 5 through a bracket or fixed on the filling container positioning mold 41. The positioning hole 12 is adaptively sleeved on the outer periphery of the filling container positioning mold 41 for position positioning to ensure the installation accuracy of the annular base 1.

[0046] In some embodiments, the tops of a plurality of guiding column assemblies 2 all have a conical section 212 along their height directions, and the conical sections 212 enclose to form a frustum-shaped rough positioning guiding channel 2111.

[0047] By designing the top of each guiding column assembly 2 as a conical section 212, the frustum-shaped rough positioning guiding channel 2111 can be constructed, which is convenient for processing and manufacturing and has a low manufacturing cost.

[0048] Specifically, a plurality of guiding column assemblies 2 are preferably cylindrical, and the conical section 212 is processed at their tops. A plurality of guiding column assemblies 2 are arranged vertically, and their plurality of conical sections 212 enclose to form a frustum-shaped rough positioning guiding channel 2111 with a large upper part and a small lower part.

[0049] In some embodiments, the guiding column assembly 2 includes an elastically liftable guiding column 21 slidably connected to the annular base 1 along the height direction of the annular base 1;

[0050] The top of the guiding column 21 has a conical section 212 along its height direction; the top end of the conical section 212 is a downward pressing end 2121 that can abut against the film heat-sealing press head 6; the downward pressing end 2121 can descend to be flush with the sealing surface at the upper end of the container opening of the container 4 to be filled under the pressing and pushing action of the film heat-sealing press head 6.

[0051] To avoid interference between the guide post 21 and the diaphragm heat-sealing press head 6 during the heat-sealing of the sealing diaphragm, the guide post 21 is designed as an elastically liftable guide post, so that when the diaphragm heat-sealing press head 6 abuts against the lower pressing end 2121, the guide post 21 can synchronously descend with the descent of the diaphragm heat-sealing press head 6; the lower pressing end 2121 can descend and yield to the upper sealing surface of the container mouth of the container to be filled 4, so as to ensure that the diaphragm heat-sealing press head 6 can smoothly press and heat-seal the sealing diaphragm on the container mouth of the container to be filled 4. During the descent of multiple guide posts 21, the peripheral wall of the cylindrical precise positioning guide channel 2112 thereof can contact and friction the periphery of the sealing diaphragm, so as to ensure that the position of the sealing diaphragm is accurately positioned and the bottom surface always fits on the upper end of the container mouth.

[0052] In some embodiments, the guide post assembly 2 further includes an elastic assembly 22. One end of the elastic assembly 22 is arranged on the annular base 1, and the other end is connected to the lower end of the guide post 21, so that the guide post 21 can elastically lift and lower along the height direction of the annular base 1.

[0053] The elastic assembly 22 functions to provide a lifting elastic force for the guide post 21. During the upward resetting process of the diaphragm heat-sealing press head 6 after the sealing is completed, the elastic assembly 22 drives the guide post 21 to rise and reset, so as to continuously perform the positioning operation of the sealing diaphragm.

[0054] In some embodiments, a plurality of guide through holes 11 are formed in the annular base 1 along the height direction, and the guide posts 21 are respectively and slidably inserted into the plurality of guide through holes 11 in a matching manner; the elastic assembly 22 is a spring that is sleeved on the lower end of the guide post 21 in a matching manner, and its upper end is corresponding to the lower part of the cylindrical precise positioning guide channel 2112 and is fixedly connected to the guide post 21, and its lower end abuts against the top end of the annular base 1 to provide an elastic force when the guide post 21 lifts and lowers.

[0055] The guide through holes 11 play an accurate guiding role in the lifting and lowering of the guide posts 21, and a spring is sleeved on the guide posts 21 to provide an elastic force, and the structure is more compact.

[0056] In some embodiments, the diameter of the bottom end of the guide post 21 is larger than the aperture of the guide through hole 11.

[0057] The diameter of the bottom end of the guide post 21 is larger than the aperture of the guide through hole 11, which can prevent the guide post 21 from disengaging from the guide through hole 11 when rising upward.

[0058] Specifically, both the guide through holes 11 and the guide posts 21 are eight. There is a sufficient lifting and moving interval between the bottom end of the guide post 21 and the upper end surface of the filling table 5.

[0059] Another embodiment provides a sheet film sealing machine, including a sealing diaphragm positioning device for a filling machine, a diaphragm heat-sealing press head 6, a press head lifting mechanism, a diaphragm suction cup 7, a robotic arm 8 and a diaphragm placement container 3;

[0060] The container 4 to be filled is arranged on the filling table 5; the annular base 1 is sleeved on the outer peripheral side of the container 4 to be filled; the bottom port of the cylindrical precise positioning guiding channel 2112 corresponds to the top end of the container opening of the container 4 to be filled;

[0061] The press head lifting mechanism, the robotic arm 8 and the diaphragm placing container 3 are all arranged on the periphery of the filling table 5; the hand of the robotic arm 8 is equipped with a diaphragm suction cup 7 to drive the diaphragm suction cup 7 to suck the sealing diaphragm 31 from the diaphragm placing container 3 and transfer the sucked sealing diaphragm 31 to the upper part of the corresponding frustum-shaped rough positioning guiding channel 2111 for release;

[0062] The diaphragm heat-sealing press head 6 is installed at the lifting end of the press head lifting mechanism, and its bottom end corresponds to the upper part of a plurality of guiding column assemblies 2. It can descend to press and drive the plurality of guiding column assemblies 2 to descend, and press the sealing diaphragm against the top end of the container opening of the container 4 to be heat-sealed. When the diaphragm heat-sealing press head 6 rises, there is a certain distance between it and the upper end of the guiding column assembly 2 to ensure enough space is reserved for the robotic arm 8 to place the sealing diaphragm.

[0063] When a diaphragm sealing machine of the present utility model is in use, the sealing diaphragm is sucked and released by the diaphragm suction cup 7. The robotic arm 8 can place the sealing diaphragm directly above the frustum-shaped rough positioning guiding channel 2111 for release. The frustum-shaped rough positioning guiding channel 2111 can guide and correct the placement deviation of the sealing diaphragm, so that the sealing diaphragm can smoothly enter the cylindrical precise positioning guiding channel 2112 and accurately fall on the top end of the container opening of the container 4 to be filled. The press head lifting mechanism can drive the diaphragm heat-sealing press head 6 to move up and down. The bottom end face of the diaphragm heat-sealing press head 6 presses against the top end of the guiding column assembly 2, so that the guiding column assembly 2 descends to avoid the diaphragm heat-sealing press head, and finally the diaphragm heat-sealing press head 6 presses and heat-seals the sealing diaphragm.

[0064] Specifically, the filling table 5 is an annular rotatable filling table, which can be driven by a rotation driving mechanism to rotate around the central vertical axis; a plurality of filling container positioning molds 41 are evenly distributed in the circumferential direction of the upper end face of the filling table 5.

By driving and controlling the rotation of the filling table 5 by the rotation driving mechanism, multi-station sequential continuous sealing operations can be realized.

[0065] Specifically, the press head lifting mechanism, the robotic arm 8 and the rotation driving mechanism are all selected from existing products.

[0066] Specifically, when the bottom end face of the diaphragm heat-sealing press head 6 descends, it can press against the lower pressing end 2121 of a plurality of guiding columns 2, so that the lower pressing end 2121 descends to be flush with the sealing surface at the upper end of the container opening of the container 4 to be filled, and press and heat-seal the sealing diaphragm at the top end of the container opening of the container body 42 to be filled positioned in the filling container positioning mold 41.

[0067] Specifically, the container body 42 can be a yogurt box that needs to be sealed with a film sheet, or can also be other box bodies or bottle bodies that need to be sealed with a film sheet, etc.

[0069] In some embodiments, the sealing film sheet is an electromagnetic induction sealing film sheet.

[0070] Specifically, the film heat-sealing press head 6 is designed with reference to the prior art, and its structure and working principle will not be described in detail here; the sealing film sheet is selected as an electromagnetic induction aluminum foil sealing film sheet in the prior art.
